Question

Do you know how to stop a crying baby?

Answer 1

Good, but rocking at a 45-degree angle (with the baby looking up) also helps.

It would be interesting to do a scientific study of the relative efficacy of the two methods. 

Answer 2

I am no mother, but it does sound interesting.

Answer 3

Interesting, indeed.

I can only add some recommendations about the opposite case, risks and safety:
